Abstract

Se propone una composicion en fase esencialmente solida que tiene como componentes, un polímero orgánico hidrofílico líquido, una solucionde sales acuosas que contiene por lo menos un elemento metálico o metaloide, y un agente coagulante. La composicion al calcinarla proporciona un polvo quecontiene dichos metales con partícula de tamano promedio de un micrometro o menos. Dichos polvos que contienen metales son de valor en la preparacion decatalizadores industriales, en cerámica, componentes electronicos, o como relleno de plásticos, pinturas o cosméticos. Esencialmente, se trata decomposiciones que comprenden: a) un polímero hidrofílico líquido; b) una solucion acuosa de sales que contienen por lo menos un elemento metálicoo metaloide; donde la composicion comprende además (c) un agente coagulante, y dichas sales está presentes en cantidad suficiente para proporcionar a lacomposicion con contenido de dichos elementos metálicos o metaloides de por lo menos 1por ciento en peso en base al peso total de la composicion.
